ΦΩΤΟΧΗΜΙΚΗ ΚΑΙ ΗΛΕΚΤΡΟΧΗΜΙΚΗ ΜΕΛΕΤΗ ΤΗΣ ΜΕΤΑΦΟΡΑΣ ΚΑΙ ΑΠΟΘΗΚΕΥΣΗΣ ΕΝΕΡΓΕΙΑΣ ΜΕ ΕΝΩΣΕΙΣ ΣΥΝΑΡΜΟΓΗΣ ΤΟΥ ΣΙΔΗΡΟΥ (ΙΙΙ)

ENERGY TRANSFER AND STORAGE BY TRIS (B-DIONATO) IRON (III) COMPLEXES WAS SHIFIED PHOTOCHEMICALLY AND ELECTROCHEMICALLY. THE EXPERIMENTAL METHODS EMPLOYED WEREPOLAROGRAPHY, CYCLIC VOLTAMETRY AND LASER FLASH PHOTOLYSIS. THE RESULTS OF THEELECTROCHEMICAL STUDY SHOWED THAT THE ELECTRON ACQUISITION, BY THE TRIS (B-DIONATO) IRON (III) CHELATES IS REVERSIBLE REACTION. IT WAS ALSO FOUND THAT A LINEAR RELATIONSHIP EXISTS BETWEEN THE REDUCTION POTENTIALS AND THE Σ6Χ HAMMETT PARAMETERS OF THE SUBSTITUENTS OF THE CHELATE RING. THE FLASH PHOTOLYSIS SHOWED THAT THE DECAY OF THE TRIPLET STATE OF ORGANIC COMPOUNDS BY THE COMPOUNDS FE (ACAL-CL)3 AND FE (BDO)3 WAS DUE TO ENERGY TRANSFER TO THESE COMPOUNDS. AS A RESULTTHE EXCITED STATES 4T1G, 4T2G, 6CT OF THE COORDINATION COMPOUNDS WERE PRODUCED. IT WAS ALSO FOUND THAT REVERSIBLE ELECTRON TRANSFER TAKES PLACE, IN A LIMITEDSCALE, AND THAT THE CONTRIBUTION OF THIS MECHANISM DEPENDS ON THE REDUCTION POTENTIAL OF THE COORDINATION COMPOUNDS.
